Be the Firebender You Want to See in the World

As with all the many, many, many flamethrower projects we’ve featured before, we’ve got to say this is just as bad an idea as they are and that you should not build any of them. That said, [Sufficiently Advanced]’s wrist-mounted, dual-wielding flamethrowers are pretty cool. Fueled by butane and containing enough of the right parts for even a minimally talented prosecutor to make federal bomb-making charges stick, the gauntlets each have an Arduino and accelerometer to analyze your punches. Wimpy punch, no flame — only awesome kung fu moves are rewarded with a puff of butane ignited by an arc lighter. The video below shows a few close calls that should scare off the hairy-knuckled among us; adding a simple metal heat shield might help mitigate potential singeing.

It may be a clever safety feature if you have to simultaneously hold a button and punch hard. Also the whole point is the punch measuring feature. It could be done witu no arduino, but why do that when you have one lying around?

People already moaning about an arduino being involved…. For every complaint as such, the maker using an arduino should just for the sake of the HaD audience, get a core i7 gaming board, a 12V to 5v+3v3 (Source-able from blown corsair PSUs for example) and power it and the contraption with a +/-12V Li-ION battery pack in a back pack.

That reminds me: I know rubbing alchohol has enough water in it to consume a lot of the heat and make it pretty safe. Is there any way to do that with a gas? Or is it impossible because you don’t have any more phase transitions to dump heat into once you’re already using gas.
